Check whether there is a problem with the network first. We can try to look at wifi or 4G networks instead. Sometimes it may be because the network is too slow to open the application. Check whether there are other versions of the software, please try to use another version (probably because the downloaded software is compatible with the mobile phone software). There are too many programs running in the background. Please stop running unnecessary software programs in the background, and often clean up the background to improve the running speed of the mobile phone.
